the proof is this -
anyone I know who has used Purolite in the past but has also used other resins will not use purolite again.
our own findings indicate that dowex outperforms purolite completely, lasting roughly 3 times as long - I don't expect anyone to take this as scientific fact but we don't buy purolite anymore.
when nearly all the major suppliers supply purolite you have to look at why - simple, it just won't last that long so they gotta keep coming back.
